摘要

分析和确定了RH精炼的初始碳含量、提升气体流量和转炉终点氧含量

并进行生产实践。结果表明

RH进站初始碳含量应控制在250×10

转炉出钢时终点氧含量应控制在250×10

-6

~400×10

。实际生产数据统计表明

在PH处理初期（0~3 min）

各炉次脱碳速率最大值可达到98×10

Abstract

The RH refining initial carbon content in liquid

rising gas rate and converter end oxygen content in liquid are analyzed and defined

and the production practice has carried out. The results show that the initial carbon content in liquid before RH refining should be controlled from 250 x 10

-6

to 400 x 10

-6

the end oxygen content in liquid of converter at tapping should be controlled from 250 x 10

-6

to 400 X 10

-6

. The statistic data of real production show that in beginning period of RH refining for 0 ~3 min

the max decarburization rate of each heat is up to 98 x 10

-6

/min

and at end of decarburization the carbon content in liquid is about 12 x 10
